PUSH-SWITCH.

Specification of Letters Patent. Patented Apr. 12, 1910.

Application filed October 27, 1909. Serial No. 524,957.

To all whom it may concern:

Be it known that I, CARL E. ANDERSON, a States of America, and residing'in the city :of Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and useful the following is a specification.

My invention relates to push switches and particularly push switches of the key type, the object of my invention being to simplify and improve the switch mechanism in the particulars pointed out.

In the accompanying drawings, Figure 1 isga vertical section through a push switch of the key type to which my invention has switch the section being taken just behind the switch piece and the mechanism being shown in a different position; Fig. 3 is a perspective view of my new rocker; Fig. 4 is a plan of the metal cross plate; and Fig. 5 is a cross section of; the latter.

In its main featnre'sthe present switch is of the common type comprising an insulating well A across t e top-of which is'spanned the'cross plateB' 7), I), through whic thej-i'key is inserted. Beneath the cross plate' B flies the switch mechanism supported uponthe\standard S carryingspin le sonwhichis .pivoted the switch piece D 'whichfissubjected to the action of the spring-d, throughthe stop lug L which is rigid-withrelationto said switch piece and which is embraced between the. ends d d of the spring (Z. The rocker R has as usual a lug 7' which'is also embraced between the ends dglk of the 'springzwhile the lugs r engage. and temporarily' detain between the .fin ersle, c, of which the 'stopll'lg L is held. fip'on oscillation of the rocker" R. the 3 ring d is tensioned and the-catch E then" reedqto .secure a sudden snap of-jthe'fswitch piece D into or out of contact'with-the' terminals T in the customary way. Y Heretofore it has been customary'to imart the oscillating movement to the rocker through links pivoted at their lower ends thereto and'subjectedat their upper ends to the action of the inserted key C. I now propose to eliminate this link with its necessary guide sleeve,

provided-with key slots substituting therefor a bearingsurface as on the rockerv with which the inp serted key m'akes'sliding contact during its actuation of the rocker. Thus in Fig. 1 it is seen that the key' bears against the end 00 while by the time the key has reached the end of its inward stroke, Fig. 2, it has traveled across the bearing surface to the other end m Obviously it is immaterial how this bearing surface is secured to the rocker R, but I prefer to form it integrally therewith as a flange struck therefrom and angled over. It is also desirable that this flange be given a curved surface, but this is not believed to be essential.

In order to key to incline from the perpendicular during the actuation of the rocker, provide a guide G beneath the key slot 6 which serves to'keep the key in perpendicular position. This guide maybe formed in any desired way, but I prefer to form it as a slotted disk at the lower end of each of the key buttons 12 and secured therewith to the cross plate B.

Obviously the invention may be embodied in structures different from that shown, and I do not limit myself to thedetails of the latter, but r I claim as my invention switch member, a'rocker and means controlled by the latter for imparting a sudden oscillation to the former, in combination with flan es on said rocker forming sliding bearings for an actuating push member.

2. Ina push switch mechanismga rocker provided with flanges adapted to form slidmg bearings for a push member, substantially as described. I

3. In apush switch mechanism, a rocker ha ing integral lugs angled over and curved to form slidin bearings for a push member, substantially as described.

4. In a key switch mechanism, a key guide comprising a hollow button with its upper face slotted to receive the key and a diaphragm spaced below the upper face of said button and slotted to form a guide for the key, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
